Application filed. November 25, 1921; semi in. 517,699.

To all whom it may ouccru:

lie it known that l, SAMUEL J. T. Mirrzcan, a citizen oi the United States, and a resident of l l illiainsport. in the county oi. llycomingr and State ot Pennsylvania, have invented certain new and us ful Improvements in Flush-Valve Constructions; and 1 do hereby declare the tollowinp; to be a ii l'lll clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in Hush valve constructions.-one object of the invention being; to so improve devices of this character as to reduce to minimum. liability of the valve rod binding in its guiding and supporting means, thus insuring: the positive and acrurate operation of the valve.

A further object is to construct the devices in such manner that the guiding means tor the valve rod may be readily secured in place but sothat said guiding means shall be positively held, normally, against possibility of such displacement as m ght result in binding oil? the va ve rod.

.31, turther object is to so construct the devices that the guiding; means for the valve rod may be easily repaired without necessity tor removing: the guiding; structure and replacing the same with a new one in the event of excessive wear of the mem ber of said guiding; structure through which the valve rod passes.

With these and other oliijccts in view, the invention co: sists in certain novel features o't construction and combinations of parts a." hereinafter set forth and pointed out in the claim.

in the accompanving drawings; Figure 1 is a view in elevation showing an embodiment oi my invention; Fi ure 2 is asectional view of the guide tube, and Figure 3 is a detail view of? the guide tube bushing.

In the drawing, 1 represents a hollow casting providing a valve seat at 2 and hav ing: a threaded coupling: shank which passes through the bottom 3 of a flush tank-a nut 4 being threaded on said shank to clamp the device to the tank bottom 3 and with said shank, an outlet pipe (not shown) may be coupled as is well understood in the art. The casting 1 is formed at one side with a hollow arm or extension 5, upon which is supported in a manner to comtlow tube 6 but is appreciably shorter than the latter so that it will not interfere with the operation of the hollow metal float com-- monly employed in lush tanks to control the operation of the water inlet valve.

Between the overflow tube (3 and the vertical rod, a cross bar 9 is disposed..-said cross bar being provided at one end with an integral collar 10 to encircle the tube 6 and at its other end with a smaller collar 11 to encircle the rod 8 and set screws 12. 13 are provided for securing the collars to the tubeand rod.

The intermediate portion of the cross bar 9 is formed with a vertically disposed. elongated guide member 1& made in the form of a tube through w ich the rod 15 of a ball valve 16 passes,-the latter being adapted normally to rest on the valve seat 2 as is well understood. The guide sleeve is maintained by its connection with the tube 6 and rod 8, in a fixed vertical position so that the free movement of the valve rod through it will be insured and it provides an extended guide for said valve rod during the vertical movements of the latter.

Within the guide sleeve. a removable bushing 17 is placed to insure the tree move ment of the valve rod which passes through it. In. the event of undue wear which might atlect the accurate operation of the valve rod and valve, the bushing 17 may be easily and quickly replaced with a new bushing and thus the device may be repaired without necessity oi"? discarding the entire guide structure and replacing the same with a new one.

In practice I prefer to so machine the ex terior of the overflow tube 6 and the rod 8 as to provide shoulders 6- and 8 respectively upon which the collars 10, 11 at re spective ends of the cross bar 9 may rest and thus support the latter in a level position from which it cannot he accidentally displaced, and insure the retention of the guide member 14: in accurate alignment with the valve rod orwire 1.5.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

In a flush valve structure, the combination with a hollow member having a valve seat, of a vertical overflow tube communicat in with said member at one side of: said va ve seat; a vertical rod carried by said hollow member at the opposite side of said 7 valve seat, said tube and rod having sheul- 5 Vders, said rod being shorter than said tube a single cross bar having collars at its respective ends secured to said tube and rod and adapted to seat on the shoulders of the sameysaid cross bar having an intermediate 10 vertical elongated guide member, a bushing in said guide member a valve, and :1 valve rod passing through said bushing and enthe same from end to end thereof.

In testimony whereof, I have signed this specification in the'pi'esence of two Sul3 15 scribing Witnesses.
